Hi
I was wondering if someone could please help me with a command for
calculating the dot product of two (NxN) matrices.
For example, for two (2x2) matrices, A and B, we define the dot product
as:
A(1,1)*B(1,1) + A(2,1)*B(2,1) + A(1,2)*B(1,2) + A(2,2)*B(2,2)
i.e. we multiply corresponding entries of the matrices and sum these
values.
It is easy to write this in a loop but for large matrices the
calculation is rather slow.
Is there a Mathematica function that I can call that will allow me to do
this faster?
Thanks
Calum
